A rock is a solid, inorganic, naturally-formed substance without a particular atomic structure or chemical composition. It is made up of two or more minerals aggregated together. Hope this answers the question. Have a nice day. Feel free to ask more questions.
According to this question, a substance with a high volatility readily evaporates.
<h3>What is volatility?</h3>
Volatility is the characteristics of a material which describes how readily the material undergo vaporization.
Volatile substances readily change phase from solid or liquid to gases via the process of vaporization.
Therefore, according to this question, a substance with a high volatility readily evaporates.

Answer:
<h3>0.2498mol
</h3>
Explanation:
7gN2 x 
=0.2498mol N2
Nitrogen gas has the formula so therefore that means you would have to multiply the mass in the molar by 2. To solve for the number of moles you need to cancel out the grams, you do this by using the molar mass of nitrgoen gas. You get the value on in the denominator from the periodic table (atomic mass of element). The grams will cancel out, leaving you with the number of moles when you divide 7/2(14.01).
Well cars need gas to run on if the car does not have gas it wont run and you cant get to places you need to go only if you have gas.
